Individual Differences in Plate Wasting Behavior: The Roles of Dispositional Greed, Impulsivity, Food Satisfaction, and Ecolabeling.

This study examines the effects of dispositional greed, impulsivity, food satisfaction, and ecolabeling on consumers' plate waste in all-inclusive hotels. Using a moderated mediation research model, a cross-sectional survey was conducted among 1253 tourists of different nationalities, all staying in five-star hotels in Alanya, Türkiye. The results show that both dispositional greed and impulsivity positively predict and significantly contribute to plate waste. Conversely, food satisfaction was found to be an influential variable that moderates the effects of greed and impulsivity on plate waste, highlighting its critical role in waste reduction strategies. Ecolabels, despite their intended purpose, were not found to have a significant impact on consumer attitudes toward plate waste. Future research is encouraged to explore strategies to counteract dispositional greed and impulsivity, given their significant impact on plate waste behavior. At the same time, refining methods to promote food satisfaction and the effective use of ecolabels may contribute significantly to reducing plate waste in all-inclusive resorts. This research contributes to our understanding of the psychological factors that influence consumer behavior in buffet settings and provides guidance to hospitality industry practitioners seeking to reduce waste.
